In the 37th year of Yong'an's great destruction, Shen Qingci witnessed the death of his father and brother. As the princess of the subjugated country, he was reduced to a prisoner and was brought back to the house for house arrest by Xiao Che, the prince of Dajing. One was an orphan from the previous dynasty who bore the hatred of the country's enemies and was bent on revenge but could not help himself. The other was a victor who conquered the enemy's country with iron-blooded skills, but secretly had complicated feelings for the daughter of his enemy. The cage of the car failed to lock Shen Qingci's pride. She hid the fire of resurrection and tried to resist and escape repeatedly, but she saw the struggle behind his calm mask in each confrontation. Shen Qingci's tenacity and purity also caused waves in his heart, making him sway between machinations and heartbeats. When the emotions of Nanjing rescue became a problem that the two had to face together, the justice of the family and country collided with personal emotions, and they were forced to embark on a journey full of trials and games. From the cold ball court in the imperial city to the beacon-fired border gates of Nanjing, from tit-for-tat enemies to confidants, Shen Qingci and Xiao Che must not only fight against the crushing fate of fate, but also face the sinking of their hearts in the torrent of troubled times. The hidden secret, the unquenched ambition for resurrection, and the deepening emotional entanglement tightly entwine the fate of the two people in the palace where fishing is prohibited and under the swaying moonlight, composing a desolate tragedy about redemption and choice, love and hate.
